Question
Microwave ovens use microwave radiation to heat food. The
energy of the microwaves is absorbed by water molecules in
food and then transferred to other components of the food.
(a) Suppose that the microwave radiation has a wavelength
of 11.2 cm. How many photons are required to heat 200 mL of
coffee from 23 to 60 °C? (b) Suppose the microwave’s power is
900 W 11 watt = 1 joule@second2. How long would you have
to heat the coffee in part (a)?
